Application filed. September To all whom it may concern:

Be it known that I, Josnrrr F Sonmrnn, a. citizen of the United States, residing at lVorcestcr, in thecounty of \Vorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in a' Drive Mechanism for Winding Machines, of

which the following, together with the accompanying drawings, is a specification.

My invention relates to an improved drive mechanism for winding machines and is particularly adapted for use in connection with machines, such as tape condensers and apron condensers, which deliver roving, or yarn, to be wound on suitable spools at the delivery end of the machine.

The object of myinvention is to provide an improved driving mechanism whereby the winding spools may be rotatably driven by means of drums in peripheral engagement with the material being wound on the spools. Specifically, my invention provides an arrangement. whereby spools provided with heads of relatively large diameter may be driven by drums of a reduced diameter which is approximately half that of the spools, thus making it possible to mount the driving drums between the condenser frames with sufficient spacing therebetween to per.- mit the operator to reach between the drums to care for the machine. The above and other advantageous features of my invention will hereinafter more fully appear, reference being had to the accompanying drawings in which Fig. 1 is a view in rear elevation of a portion of a condenser providedwithdrums and spools driven in accordance with myinvention.

Like reference characters refer to like parts in the various figures.

Referring first to Figs. 1, 2 and 3, a por tionof a tape condenser is shown as compr sing spaced end frames 1, 1, between. which are supported a number of pairs of cooperating winding spools and driving drums 3, the spools 2 being so supported as to receive the rovings, or yarn, from the 1.

invention which, of course, may be used 7 with other types, of machines employing winding spools. In machines of this type,

it has been heretofore customary to drive the drums 3 directly by means of pulleys mounted on-the shafts of the drums,ibut with this arrangement, it has been found necessary to make the drums of substantially the same diameter as the spool heads in order that the periphery of each drum may engage theperiphery of the barrel of any empty spool. The object of the presentinvention is to provide an improved mechanism for driving the drums 8 in such a manner that the diameter of the drums may he reduced to substantially onc-half the diameter of the spool heads 4:, thereby permitting such a spacmg of the driving drums as to ive read access to the ooeratin )arts of l r; i

the machine.

With my improved drive mechanism, each drum 3 is rotatably supported at its ends by means of brackets 6 mounted on arod 7 extending across the machine between the frameimembers 1, and as each bracket 6 is constructed in exactly the sanie manner, only one bracket will be described in detail, with reference to-Figs. 4c, 5 and 6, which show onlya portion of a drum 3 and its associated parts, on an enlarged scale.

As best shown in Figs. 5 and 6, each bracket 6 arovides. an uawardl 1 extendin portion 8 which is bent laterallyat 9 to permit the reception of a cylindrical bearing within the open end of the drum 8, it being evident from Fig. 1-, that each pair of brackets 6 provides oppositely facing bearings 10. In order to receive support from the bearings 10, the drum is closed at each end by a head 11 which provides a central hub portion 12 carrying a pivot stud 13, an enlarged portion 14: of which is receivcd in a bearing 10. The stud 13 is secured to the hub 12 by neans of a nut 15 coacting with a collar 16. The head 11 also provides an annular flange 17 surrounding the bearing 10, which flange 17 is provided with a plurality of spaced peripheral openings 18, whereby a driving torce may be applied to the periphery of the drum 3 by mechanism which will now be described.

- As best shown in Fig. 5, each bracket 6 also provides a longitudinally extending sleeve 19 which is located between the sup porting rod 7 and the bearing 10, and is adapted to journal a shaft which extends parallel to the axis of rotation of the drum o. The shaft 20 eXtends beyond the adjacent end frame 1 and is provided with a pulley 21, whereby may be driven from a suitable source of power, not shown. The other end of the shaft 20 carries a pinion 22, which, as best shown in Fig. 6, has its teeth in engagement with the openings 18 provided in the periphery of the flange 17 of the drum head 11. Thus, when the shaft 20 is rotated, it is adapted to also drive the drum 3- and with it the associated spool 2, by reason of the frictional engagement be tween the surface of the drum 3 and the barrel 5 of the spool 2,- or the material being wound thereon, it being evident that the heads 1 of the spool 2 entirely clear the brackets 6. 1

In order to further support each bracket 6, one end of the sleeve 19 which journals the shaft- 20 is received in the boss 23 or a hanger 2a which is carried on a stud 25 received in the adjacent end frame 1. As best shown in Fig. 2, the end frame 1 provides a number of vertically spaced arms 26, each having a notch 27, which on existing inachines formerly served to support the shaft of a driving clru-n1. In my improved ar rangement however, the notch 27 receives the stud 25 which is clamped therein by means of nuts 28. ,The end of the stud'25 is received in an elongated opening 29 provided in the upper end of the hanger 24, so that the hanger 24: may be clamped in different .po'- sition's on the stud 25 by means of a nut 30 cooperating with a shoulder 31 provided on the stud.

From the foregoing, it is evident that each or the drums 3 is adapted to be supported between the end frames 1 of the machine in such a manner that a rotative driving force may be applied to the outer periphery thereof by a shaft disposed entirely beyond the enlarged heads 4 of the spool 2. With this arraigement, it is possibleto employ a drum which is appr xiinately halt the diameter of the spool heads t, thereby giving plenty out room between the drums 3 for access to the parts of the machine. The driving mechanism of the present invention is therefore a distinct improvement over previous driving mechanisms, for the same purpose, in which the driving drums have been rotatably supported in the slots of the arms 26 oi the end frames and the driving force applied dircctly to the axes of the drums.

liiyinvention possesses a further advantage in that it may be readily applied to .ing machines without necessitating any rearrangement of the e ntial parts thereof, it only being necessary to provide the cross rods 7 for supportingthe brackets 6 for the drums 3; It is evident that the brackets 6 are capable of ready adjustment for supporting the drums 23 in proper position, by the provision of the set screws 32 for clamp-- ing each bracket 6 to its rod 7. Furthern'iore, each hanger 2% permits proper positioning of the sleeve 19-thcrein by means of a set screw 3-3, while the hanger itself is adapted for adjust-n'ie'nt with respect to the end frame through the provision of the elongated opening 25) for receiving the stud Thus each drum 3 and its driving mecha nism may be readily installed and adjusted between the end frames of a machine to drive a winding spool 2 supported in the proper position to receive the materiai to be wound thereon. In order to properly position the winding spools 2, a number of pairs of spool supportingari 3% are mounted on the rods 7 beyond the brackets 6, the arms 3a providing inclined portions 35, against which bear the stub shafts 36 provided by the ends of the spools 2, is clearly shown in Fig. 2. The arm portions serve to guide the upward movement of the spool barrels 5 away from the drums 3 as the material is wound on the barrels 5 by the rotation of the drums.
